They are then drawn upward into said seats, the square portions engaging between the holes above said seats. It will noiv be impossible to Withdraw the bolts from the holes, as the ends of the .heads project beyond the sides of the boltholes. The shanks of the bolts pass through slots in the clips and are engaged by the nuts. To remove the bolts, the nuts are loosened, and then they are given a quarterturn backward, when the heads of the bolts and the bolt-h0les will come into longitudinal alinement, When they can be readily Withdrawn.

IIaving thus fully described my invention, what I claim isl. As an improved article, a metallic railway-tie, provid ed Wi th a central longitudinal strengthening-rib, and formed near each end with rectangular boltlioles having do\vn- Wardly-depen ding parallel lian ges recessed to form seats opposite to each other, substair tially as described.

As an improved article a metallic rail- Waytie, having downwardlydepending side flanges, downwardly-curved endsa central longitudinal strengthening-rib on its under side, and formed near each end With rectangular bolt-holes, having doWnwardly-depending parallel sides or flanges, provided with opposite seats or recesses, substantially as described.

3. The combination Wi th a metallic railwaytie, having a central longitudinal strengthening-rib on its under side, formed with rectangularl bolt-holes near each end, and dowlr wardly-depending sides or flanges, formed with reinforced seats or recesses registering with each other, of the bolts, comprising the elongated heads, the square shoulders and the screw-threaded shanks, substantially as described.

LI. The combination with a metallic railwaytie, having a central longitudinal strengthening-rib on its under side, formed With rectangular boltholes near each end, and downwardly-depending sides or flanges, formed with opposite alined reinforced seats or recesses, of the bolts having elongated heads, and shoulders and theinclined screw-tjhread ed Shanks, the clips having beveled upper sides and the nuts, substantially as described.

In testimony whereof I aiiix my signature in presence of two Witnesses.
